Brian From Silver Lake KS

i have two of these subs in a custom ported box that's wired in a series
and hooked up to a sony XM-1252GTR amp and
these subs are BUMPIN hard, loud, and clean. My whole dash literally shakes up and down when it hits the low low bass. Very good subs for only 140$ a pair

Overall this subs are great, I have two of these powered by a 1600 watt amp and a 1.5 farad cap and the bass is realy loud, alarms be going off when I set the volume at 20 out 32, the quality of the bass is unbeliveable and the price is great Sony Xplod is the best sub for the price, I highly recomend this sub to anyone who wants hard hitting bass without compromising quality on a tight budget.
